VEHICLE-BRAKE.

Application led September 16, 1913.

T0 all wlw/n it may concern Be it known that I, ARMIN G. HnLrrn, a citizen of the Republic of Switzerland, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Vehicle- Brakes, of which the following is a specification.

The general object ofthis invention is to effect the instantaneous stopping of a vejar or shock resulting therefrom. And to these ends the invention consists of a'pair of spring-actuated pivoted shoes adapted to be swung downwardly and under the rear wheels of the vehicle and shock absorbing elements connected lto the said shoes.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specilication, reference being had to the accompanying drawings forming part thereof, in which Figure 1 is a side elevational view of my invention attached to a motor vehicle shown in dotted lines and, Fig. 2 is a perspective view of the skids or shoes and operating mechanism shown disconnected from the vehicle. y

The brake consists of the shoes 5 and .6, the operating mechanism c and the shock absorbers d.

The shoes 5 and 6 are each provided with the channel portion 7 which admits of the shoe straddling the wheel of the vehicle. The under face 8 of the shoe is relatively `flat, and is provided with the teeth 9; these teeth are also mounted at the sides, adjacent to the under face, and are provided so as to bite into the surface of the road when the brake is applied. The shoe also is provided 10, by which it is pivoted to the arm l1; these arms are connected at their upper ends by the rod 12. This rod may be journaled in any suitable manner in the chassis of the vehicle so that when turned, it will swing the arms forwardly and rearwardly. A lever 13 is secured to the connecting-rod andiis connected to a second lever 14 by the cable 15. The second named lever .14 is rigidly secured to the handle 16 by the rod 17, which is mounted on the frame of the vehicle, adjacent to the operators seat, so tljat the handle will ne within easy'reach of the operator. It will Specification of Letters Patent.

be noted by referring to' the drawings, that i the lever 14 and the handle 16 cooperate to form a bell-crank.

The shock absorber d consists of a barrel 18, having one end closed and provided at its opposite end with a longitudinallydisposed ear 18. A rod 19 frame of the vehicle, is pivoted to the ear and supports the ear-end of the barrel. The closed end of the barrel is bored to receive one end of a shaft 20 which functions as a plunger for the .barrel and is connected at its op osite end to the lower end of the arm 11. he end of the shaft inserted in the barrel is provided with a knob and carries the washer 21, which bears against the yspring 22 when the plunger is drawn outwardly. A spring 23 is secured to a sleeve carried by the arm 11 vand has its other end connected to the frame of the vehicle. This spring is tensioned when the brake is oil and will when desired, cause the brake to assume the position shown in full lines in Fig. 1.

As shown in Fig. 1 the dotted lines show the brake in the inoperative position The stop 24 limits the backward movement of the handle 1G, and it will be seen the lever 14 is oil' center. This position prevents the automatic return of the handle to the position shown in full lines, as the tendency of the spring will be to cause the handle to go back farther. Obviously the handle will remain set until pushed over by the cliunfenn When the brake is oil', the shaft il? vill he progressed farther into the barrel are spring 22 will be expanded upon "ne handle being turned over from the dot tion to full line position. The above described will swing the s wardly and under tlf movement occurs, the l drawn 'from the barre beingy ccmpresseifl. Thi spring softens the su and absorbs the shock ai g from in" stantaneous application el". trie brakes.

What is'claiined as new ist In combination with a wheel mount-cd vw llicle, a. brake comprising a rod ournaled to .the body of the vehicle, a lever fixed to the l the depending from the is swung, means operatively connecting the free end of the first mentloned lever with the working end of the bell crank lever, an arm fixed to said rod, a shoe carried by the arm and adapted to pass under the wheel of the vehicle when the rod is turned, a spring connected at one end with the arm and at its other end with thebody of the vehicle.

and being under tension to normally hold the shoe toward the Wheel, a shock absorber including relatively movable members one of which is connected with the body` of the vehicle and the other connected with the free end ortion of the arm and a s ring engaging oth of said members and lieing 15 under tension with a tendency to draw the shoe away from the wheel.

In testimony whereof I afx in presence of two witnesses.
